Summary

• Description:

  The PDF document comprises THE SUPER LEAGUE JOINT NATIONAL MOCKS Chemistry Paper 2 2026 Mock Exam with Answers (Marking Scheme). The marking scheme is in a different document.

  It was a KCSE Chemistry 233/2 examination.

  This structured paper provides an in-depth assessment of inorganic trends, chemical thermodynamics, electrochemistry, industrial metallurgy, and organic reaction pathways. It tests higher-order analytical reasoning through graphical analysis, stoichiometric deductions, and industrial flowcharts.

  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 7 (Questions 1 to 7)
  • Structure: A comprehensive theory paper comprising seven compulsory structured, graphical, and data-based questions carrying varying marks totaling 80 marks.

  It covers the following topics:

  • Periodic Table and Periodicity (Periodic trends, valence, ionic radii, ionization energy, stoichiometry of metal-acid reaction, melting point trends of halogens)
  • Thermochemistry and Energetics (Heating value of fuels, Hess's Law enthalpy calculations for ethyne combustion, Born-Haber cycle/lattice and hydration energy for calcium chloride, energy level diagrams)
  • Nitrogen and Its Compounds (Laboratory preparation of dinitrogen monoxide, reactions with magnesium ribbon, industrial uses of nitric acid, stoichiometric yield of ammonium nitrate fertilizer)
  • Solubility and Solubility Curves (Solubility table completion, solubility curve plotting of potassium chlorate, fractional crystallization analysis)
  • Electrochemistry and Electrolysis (Standard electrode potentials, reference half-cells, electrochemical cell representation, Faraday’s laws of electrolysis and electroplating calculations)
  • Industrial Metallurgy of Iron (Blast furnace zones and reactions, charge mixture constituents, functions of tuyeres, cast iron vs wrought iron, nuclear decay of iron-60)
  • Organic Chemistry and Environmental Impact (Isomerism of alkynes, condensation polymerization of nylon, ozone layer depletion by CFCs, dehydration of alkanols, chemical differentiation between alcohols and carboxylic acids)
